Hi,
I spent quite some time browsing through the posts on this problem and also tried a lot of suggestions which did not work. Then I read July 14, 2022 JeffBakst post which described exactly my problem and decribed he disabled Malwarebytes and disabled .Net 3.5 etc. I started to disable Malwarebytes alone and it did not work.. Then I disabled .Net 3.5, restarted my device and the update worked. I did not guess it was .Net 35, nor did I invent anything. I simply tried what JeffBakst suggested which did work for him.
At least it worked for 3 individuals and probably more. For me tends to prove it was it. And this is a much simpler solution than Inplace installing OS over OS.

Hi,
I had the same problem. I first deactivated Malwarebytes but this did not resolve the problem. I then turned off .Net 3.5 and restarted my device. Then installed the 2002-07 Cumulative update KB 5015814 for Windows 11 via Check for updates and IT WORKED !! It took longer to download and install than usual but IT WORKED. I then reactivated .NET 3.5 and Malwarebytes.
For me it sounds it was a problem with .Net 3.5 since deactivating Malwarebytes only did not do the job.
I hope it helps others.

I deinstalled Malwarebytes but that did not help
I turned off .NET3.5 as well and that worked
What gave your the idea to disable .NET3.5 I would have never guessed
I had the same problem, and none of the tips found on the internet helped. Sfc, dism, manual install from the catalog, etc... No success. Even an in-place upgrade with the win11 ISO did not work.
What finally worked for me, is to do this in-place upgrade, after disabling all non-microsoft services.
- download win11 ISO
- run msconfig:
> on the tab General, chose Selective Startup, with only Load System Services checked,
> on the tab Services, check Hide Microsoft Services, and then Disable All.
- mount the ISO, run setup.exe
- let the installer do its job, keep apps & files. takes some time ...
- when done, run msconfig again and re-enable all non-microsoft services
After all this, win update shows that KB5015814 is successfully installed.
Hope this helps others!
Perfect, thank you this worked when nothing else did.
